Hint: We need to know that a compound that has chemical formula C5H12O is a neopentyl alcohol. An alcoholic derivative of neopentane is neopentyl alcohol. A hydrocarbon group that has a quaternary carbon linked to three groups of methyl and one group of methylene is a neopentyl group.

Complete step by step answer:
We can draw the structure of neopentyl group as,

The chemical formula of neopentyl alcohol is (CH3)3CCH2OH. As it is derivative of alcohol, it structure would be:

We know that carbinol is a primary alcohol that contains the molecular formula CH3OH. Methanol would be also called “Carbinol” in its nomenclature. In neopentyl alcohol, a carbinol group is also present and a tertiary group is also found. Therefore, tertiary butyl alcohol is the derived name of neopentyl alcohol.

So, the correct answer is Option C.

Additional Information:
A primary alcohol is carbinol. There are some variations between methanol and carbinol.
The simplest aliphatic alcohol is methanol.
We can use methanol as a solvent and is colorless, inflammable and toxic liquid.
The solubility of methanol in water is partial but it is dissolvable in alcohols, ethers and several organic solvents.
Methanol has the ability to react with strong oxidants.
We can use methanol as a chemical intermediate for the preparation of surfactants, cleaning of compounds, and lubricants.

Note: We need to know that the 2,2-dimethylpropan-1-ol is the IUPAC name of neopentyl alcohol. The other names of neopentyl alcohol are neo amyl alcohol and neopentanol. There is a chance that you can make a mistake by choosing option (A) and (b). In an iso group all the carbon other than one carbon forms a straight chain whereas in neo group two carbons form a straight chain, and that’s why it is known as tertiary butyl carbinol.
